Which is a QoS model that a network engineer would implement to ensure a source to destination quality of service standard for a specified data flow?

  • differentiated services
  • integrated services
  • low latency queuing
  • class-based weighted fair queuing
  • best effort

Explanation: Best effort is the default packet forwarding design and provides no QoS. The differentiated services model enforces and applies QoS mechanisms on a hop-by-hop basis, not source to destination. Class-based weighted fair queuing and low latency queuing are queuing algorithms.
